FAQ's

As a result of sequencing, the authenticity of ATCC® HTB-17™ has been questioned by R.F. Petersson in Stockholm and collaborator E.G. Van Meir in Atlanta (personal communication and see Ishii, N., et al. Brain Pathol 9: 469-79, 1999). They report similarities between U-373 MG (ATCC® HTB-17™) and another glioblastoma, U-251. The cell line U-373 MG, obtained from the original lab in Uppsala has differing genetic properties from the ATCC® HTB-17™ (U-373 MG). Following further investigations, ATCC stopped distribution of this cell line.
